71. Yvonne Strahovski
Biggest accomplishment this year: Reprising her role as Hannah McKay in the final season of Showtime's Dexter
After her role as Sarah Walker on Chuck came to a close last year, Yvonne Strahovski quickly managed to find work again with a recurring role on Dexter, playing a woman with a history of murder who also gets romantically entangled with the titular character. She's the first foil for Dexter to not die at the end of a season, so kudos to her. Strahovski will next appear in the horror-thriller I, Frankenstein along with Aaron Eckhart and Bill Nighy, as well as a return trip to Dexter for the show's eighth season. Hope as we might, we're not sure she's going to be able to survive two years in a row.
